Abstract (en)

[origin: EP3910351A1] An integrated circuit and a method of performing a built-in-self-test (BIST) procedure in an integrated circuit. The integrated circuit includes a plurality of radio circuits and a switching network for performing a built-in-self-test (BIST) procedure. The switching network includes a plurality of combiners, a plurality of transmitter connection switches, a combiner switch, a splitter switch, a plurality of splitters and a plurality of receiver connection switches. The switching network may also include a splitter bypass switch and/or a combiner bypass switch. The components of the switching network may operate to route signals between outputs and inputs of the radio circuit to implement the built-in-self-test procedure in one or more modes involving either parallel or sequential testing of the components of the radio circuits. A diagnostic mode is also envisaged.
